2 angles of a triangle are the same size. the 3rd is 3 times as large as the 1st

myrzilka [38]

Answer:

36°, 36° and 108°

Step-by-step explanation:

let the equal angles be x then the third angle = 3x

The sum of the 3 angles in a triangle = 180°, thus

x + x + 3x = 180, that is

5x = 180 ( divide both sides by 5 )

x = 36

and 3x = 3 × 36 = 108

The 3 angles are 36°, 36° and 108°

Which expression is the factored form of 2/3x+4 ?

frosja888 [35]

Answer:

Option C.

Step-by-step explanation:

The given expression is

$\dfrac{2}{3}x+4$

We need to find the factored form of the given expression.

The given expression can be rewritten as

$\dfrac{2}{3}x+(\dfrac{2}{3}\times \dfrac{3}{2})\times 4$

$\dfrac{2}{3}x+\dfrac{2}{3}(6)$

It is clear that $\frac{2}{3}$ is common.

Taking out common factors, we get

$\dfrac{2}{3}(x+6)$

It is the factored form of the given expression.

Hence, the correct option is C.
